Would it be possible to get some 4140/4142 that is prehard around 30-40rc and just heat treat the edge of a chopper I am making with a torch to non magnetic then quench in oil? Also what tempering range would I be looking at if I was shooting for 56-57? I promise I have looked but the info I can find is vague, along the lines of temper between 400 and 1200. Thats it.
Basically I want to keep the majority of the tool in the 30-40 range, but the edge at 57ish.
Thanks for your time ya'll.
